Innovation in the Application of aluminized zinc steel, aluminum coils and special steel and Evolution of Supply and Demand patterns

In the current wave of vigorous development of the manufacturing industry, metal materials, as the cornerstone of the industry, have attracted much attention for their technological innovation and application expansion. Metal materials such as Galvalume Steel, Galvanized Steel, Aluminum Coil/Pipe/Plate, Stainless Steel, Aluzinc Steel, and Prepainted Steel It is constantly bringing about innovative changes in their respective fields.

Recently, Benxi Steel Plate successfully obtained an invention patent named "A Baked Hardened Steel Plate for Electro-Galvanizing and Its Production Method", with an authorization date of May 16, 2025, and the application number being CN202211666926.5. This patent focuses on the baked hardened steel plate for electro-galvanizing applied in the automotive manufacturing field. Its unique composition design (by weight percentage, C: 0.0010-0.0015%, Mn: 0.10-0.70%, Si≤ 0.02%, Al: (0.020% to 0.050%, etc.), without adding reinforcing carbon, nitrogen binding elements or precious metals, can achieve the lightweight and high-strength characteristics of steel plates, which meets the urgent demand of the current automotive industry, especially electric vehicles and new energy vehicles, for lightweight and energy conservation and emission reduction. According to market research institutions' prediction, the market demand for electro-galvanized high-strength steel will grow at an annual rate of approximately 8% in the next five years. The acquisition of this patent by Benxi Steel Sheet undoubtedly gives it a head start in the highly competitive market.

Shandong Iron and Steel Group Rizhao Company also brought good news. Its galvanized steel plate products were successfully directly supplied to a leading domestic home appliance enterprise and were first applied to the enterprise's air conditioning products. In this cooperation, the Science and Technology Quality Center of Shandong Steel Rizhao Company, in collaboration with the Hot Rolling Plant and the Cold Rolling Plant, promptly established a research and development team. Referring to the previous experience in galvanized steel production, they determined and implemented a trial production plan for hot rolling, acid rolling, and galvanizing, achieving a successful trial production in one attempt. After rigorous experiments and control over multiple aspects such as the physical properties of the product, the adhesion of the zinc coating, and the metallographic structure, it was ensured that the product performance met the requirements. As a result, it successfully passed the multiple screenings of the home appliance enterprise and became its direct supplier of Galvanized Steel Sheet products. This not only reflects the high quality and high performance of Shandong Steel Rizhao Company's products, but also highlights its rapid response to market demands and technological innovation capabilities.

The aluminum materials sector is not lagging behind either. Chongqing Mingren Aluminum Industry Co., LTD., as a comprehensive service enterprise that has been deeply engaged in the research and development, production, processing and sales of aluminum and aluminum alloy materials for many years, continuously expands the application territory of its products. The aluminum alloy processing materials such as Aluminum Plates, coils (strips), foils, tubes, bars, profiles, forgings and wires operated by the company have been widely applied in numerous fields including aviation, aerospace, military weapons, mechanical manufacturing, power grids, petrochemicals, railway and urban rail transit, ships, automobiles, electronic appliances, communications, instruments and meters, printing, packaging, architectural decoration, cultural and sports goods, etc. In 2015, the company's warehousing, distribution and processing center located in the National Highway Logistics Base of Nanpeng, Chongqing was put into operation. It is equipped with multiple sawing, drilling, punching, milling, shearing, bending, welding and polishing equipment as well as CNC processing centers, dedicated to creating a one-stop "material warehouse" and "manufacturing workshop" for customers.

From architecture to automobiles, from household appliances to aerospace, Galvalume Steel, Galvanized Steel, Aluminum Coil/Pipe/Plate, Stainless Steel, Aluzinc Steel, Prepainted Steel Metal materials, with their respective characteristics and advantages, play a crucial role in various industries. With the continuous innovation of technology and the increase in R&D investment, these metal materials will keep making breakthroughs in performance improvement, cost control, environmental protection and energy conservation, injecting a continuous stream of impetus into the high-quality development of the global manufacturing industry. Their future market prospects are very broad and they are bound to show unlimited potential in more emerging fields.
